When I first came across the MAXXHAUL 70205 Trailer Light Kit, I was immediately impressed by how thoughtfully designed it is for trailer owners like me. This kit isn’t just a random collection of parts; it’s a complete solution that includes everything I need—two 12V LED stop, tail, and turn signal lights, two amber clearance lights, a license plate bracket, and a wiring harness.
